Illustrations
created in all major vector drawing programs have a definite
anatomy and share a common pattern. Whether you use Deneba Canvas™,
Adobe Illustrator, CorelDRAW or Macromedia FreeHand you will
find that this pattern exists even though each program may define
the parts differently. The purpose of this section of the web
site is to take apart a vector drawing so you can see how it
is put together and able to understand it. In the illustration
section is a table
of equivalent terminology to better help you translate the
terms from one application to another. This will clarify the
subject and make it less confusing. You will not be bound to
a single application once this becomes clear to you.
The pattern of vector illustrations is best viewed or represented
as a hierarchy or "tree". The illustration itself would
be at the top and its various parts would descend below it:
| An
ILLUSTRATION is composed of vector |
|
OBJECTS
each having one or more |
|
|
PATHS
which are composed of |
|
|
|
LINE
SEGMENTS having |

|
|
|
ANCHOR
POINTS at each end |
Paths:
Line Segments and Anchor Points:
In the diagram
above the OBJECT shown is composed of a single closed PATH composed
of 19 LINE SEGMENTS and 19 ANCHOR POINTS. Notice the curved line
on the bottom. It is composed of 2 separate line segments even
though it appears to be one continuous smooth line.
